you have to release alt for alt + F10 working

I will have a look at this bug. It sounds like a simple problem.

I notice in oneiric (and compiz-core) that Alt+F10 is the key combo to maximize a window. Has that been overridden/changed in precise? What is Alt+F10 expected to do in precise?

Or do you mean to use F10 to access the panel menu, and it's delayed by using Alt?

It should open the file menu (I believe).

I think the expected behaviour is that if you hold alt and tap F10 the
menu should open straight away, not wait for the alt release.

Are you saying that Alt+F10 (the compiz-core binding for maximize) has been removed in precise, or that you expect listeners for F10 to be triggered when Alt+F10 is pressed? Or both?...

It looks like this fix should help too:

I still seem to get this bug on compiz 1:0.9.7.0+bzr3035-0ubuntu1.

reverted, didn't fix it, indeed

(the status is reverted)

It seems to be correctly handled by compiz (the triggerPress() is fired at the right moment, the corresponding action as well). It looks to me like a race condition in handling the alt + F10 and the hold-alt 'make the menu appear on the panel'. Looking into this.

I just wanted to point out that Alt-F10 is severely broken, up to the point where you have to restart/replace unity from VT1 because it gets stuck in the app indicator (e.g. after Alt-F10 then just F10 or Alt-F10 again to figure out why it won't maximize).

I assume that it gets fixed in the next uploads/release(s) and just wanted to notify you about this.
